Cave Swallow nest documentation, WMWR, OK av Victor W. Fazio III

Cave Swallows returned to French Lake, Wichita Mtns Wildlife Refuge, Comanche County, OK. First detected mid-April by Lou Truex, two birds have been reported on a few occasions. Today, Dave Gagne and I took a closer look. We identified 5 fresh nests among several barn and Cliff Swallow nests at the same site as last year's nest ... an old delapidated fish ladder at the dam. At least 4 of these nests were visited several times by Cave Swallows, with two briefly occupied by two birds. However, we could not confirm more than 4 total birds present in the swirl of activity that included Barn Swallows feeding naked young and Cliff Swallows feeding young ready to fledge. This follows the same inter-species nest chronology of last year whereby Cave Swallows did not hatch until after Barn Swallows fledged.
